Step 1. Advise the customer that the system (one or more nPartitions) must be shut down for repairs.
Ensure that the customer has a current backup, and inform the customer of the anticipated
downtime.
Step 2. Login to the server MP.
Step 3. Use the Virtual Front Panel (VFP) to view the current state of the nPartition that you will shut
down.
From the MP Main menu, enter VFP to access the Virtual Front Panel menu, and select the
nPartition whose boot state you want to view.
Type
Control-b (^B) to exit the VFP display.
• If an nPartition has booted HP-UX, or if it is in the process of launching HP-UX, you must shut
down HP-UX on the nPartition.
When HP-UX is running on an nPartition, its VFP displays “HP-UX heartbeat” with a blinking
asterisk (*) to indicate its interactivity.
In this case, proceed with the next step.
• If the nPartition is at its extensible firmware interface (EFI) shell, then HP-UX has already
been shut down.
• If the nPartition currently is booting, then you should wait for it to reach the EFI shell and, if
necessary, interrupt auto-boot when you see the “Attempting to boot” and “To discontinue,
press any key within 10 seconds” messages in the console window.
NOTE The message “Attempting to boot” and “To discontinue, press any key within 10
seconds” appears in the console window and not in the VFP.
Step 4. From the MP Main menu, enter CO and select the console for the nPartition you plan to shut down.
You should have access to the HP-UX login prompt (or command line) when using the console of the
nPartition. If you have no interactivity at the console, HP-UX may be halted or hung.
Step 5. At the console of the nPartition, login to HP-UX and shut down the operating system.
After making arrangements with the customer, issue the shutdown command to shut down and
halt HP-UX on the nPartition.
For example: The shutdown -h 240 command will shut down and halt HP-UX on the nPartition
after waiting for a grace period of four minutes (240 seconds).
To reboot the nPartition after it is halted, use the RS command of MP Command menu to restart
the nPartition. (This allows the nPartition to reset and boot to its EFI shell; if auto-boot is
configured it also boots HP-UX.)
Step 6. Unplug all the power cords located on the back of the server to remove all power from the server.
